Did you try doing the oven trick on your dead GPUs. In my experience it brought about half of them back to life... for many another 3-9 months or so.
All you need to do is disassemble the GPUs from the heatsink, cover any components with aluminum foil, leave the GPU chip exposed, put it in at some desired temp and you are all set. There are videos on Youtube on how to do this. Best to use some toaster oven that you don't use.
Wait until it cools and put it back in. You will be surprised that most of the time it works. To make it last as long as possible try and don't do too many heat cycles because that kills it again. So leave you rig mining and don't shut it off too often. The more you shut it off and let it cool and then heat up again, the less hours you will get out of it.

I use a hair dryer from a soldering station for this, if friends ask for a very cheap subordinate video card, but you do not know which module needs to be heated.
My experience says that such video cards will then have to be heated every 1-2 months if they are used in mining.
9 months is an exception to the rule.
